The female reproductive system has several important functions including producing egg cells for reproduction and sex hormones. It consists of both external and internal organs working together. The internal organs include ovaries, fallopian tubes, uterus, and vagina. During puberty, girls experience physical changes in these organs and their development. The menstrual cycle and pregnancy occur through the coordinated efforts of the reproductive system. Diseases can also affect the system's normal physiology.
The female reproductive system provides several functions.
The ovaries produce the egg cells, called the ova or oocytes.
The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur.
The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
Once in the uterus, the fertilized egg can implant into thickened uterine lining and continue to develop.
If implantation does not take place, the uterine lining is shed as menstrual flow.
In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle.
During menopause, the female reproductive system gradually stops making the female hormones necessary for the reproductive cycle to work. At this point, menstrual cycles can become irregular and eventually stop.
One year after menstrual cycles stop, the woman is considered to be menopausal.

Structure and functions of the male reproductive system
Reproductive health
Reproductive system:
The organs involved in producing offspring (a person's child or children).
In women, this system includes the ovaries, the fallopian tubes, the uterus, and the vagina.
In men, it includes the prostate, the testes, and the penis.
The female reproductive system
The female reproductive system plays many vital functions that ensure the continuation of the human race
Located in the pelvic cavity
Parts:
It consist of
External genitalia
Internal genitalia
External genitalia:
Labia minora
Labia majora
Clitoris
Vaginal orifice
Internal genitalia:
Ovaries
Fallopian tubes
Uterus
Vagina
Vagina:
A muscular tube, that extends from the cervix of the uterus to the outside of the body.
During intercourse, the vagina receives the male’s penis and semen.
Birth canal that the baby passes through in a normal delivery.
Ovaries:
Small almond-shaped glands that produce ova and the female sex hormones located on both sides of the uterus within the pelvic cavity.
In charge of ovulation and producing the female sex hormones.
The hormones are responsible for getting the lining of the uterus prepared for a fertilized ovum
Uterus:
Hollow organ (also called womb)
Fetus (unborn baby) develops and grows.
Contractions to the walls propels the baby during delivery through the birth canal in a normal delivery
Parts: fundus, body & cervix
The fundus is the broad curved upper area in which the fallopian tubes connect to the uterus;
The body, the main part of the uterus,
The cervix, extends downward and opens into the vagina.
Uterus has 3 layers:
The endometrium is the inner layer
The myometrium is the middle layer
The perimetrium is the outer layer
Function of uterus:
The uterus receives a fertilized egg and protects the fetus (baby) while it grows and develops.
The uterus contracts to push the baby out of the body during birth.
Every month, except when a woman is pregnant, the lining of the uterus grows and thickens in preparation for pregnancy.
If the woman doesn’t get pregnant, the lining is shed through the cervix into the vagina and out of the body. This is called menstruation.
The function of the female reproductive System:
The female reproductive system produces ova (the female reproductive cell)
Provides a location for fertilization
Growth of a fetus
Secretes female sex hormones
The breast produce milk to nourish the newborn.
Menstruation:
Menstruation, or period, is normal vaginal bleeding that occurs as part of a woman's monthly cycle.
Every month, your body prepares for pregnancy. If no pregnancy occurs, the uterus sheds its lining. The menstrual blood is partly blood and partly tissue from inside the uterus. It passes out of the body through the vagina.
Menstrual cycle:

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
3. IMPORTANCE OF SYSTEM:
The primary function of the female reproductive system is to produce the female egg
cells which are essential for reproduction.
It is important to know that the entire system is designed for transporting the ova to
the exact fertilization site.
The female reproductive system is responsible for producing female sex hormones
which maintain the reproductive cycle.
4. INTRODUCTION
• Sexual life in females
• FIRST PERIOD
• It Extends From Birth To Puberty
• SECOUND PERIOD
• From Menarche To Menopause
• THIRD PERIOD
• From Menopause To Rest Of The Life
5. PUBERTY
• Puberty is the period of the time when secondary sexual characters begin to devolop
• In females puberty starts at the age of 12
• when First menses appears that is considered to be puberty
• Changes occurred are
• Development of pubic hair
• Development of axillary hair
• Development of breast

9. ORGANS INVOVED IN THE SYSTEM
• MONS PUBIS:
• It is a round eminence present in front of the
pubic symphysis
• It is formed by the accumulation of the sub
cutaneous fat
• It is covered by the skin and the pubic hair
• Labia majora:
• The two longitudinal folds of the skin
enclosing fat which are extending from the
mons pubis
• They are covered by pubic hair externally
and internally they contain sebaceous glands
10. • Labia minora
• Medial to the labia majora there are two
small folds of the skin called as labia
minora
• Labia minora is devoid of the pubic hair
and fat.
• There are having numerous of the
sebaceous glands
• Clitoris:
• It is the small cylindrical mass of the
erectile tissues and the nerves located in
the anterior junction of the labia majora
• It corresponds to the penis of the males
11. • VESTIBULE
• The cleft between the labia majora is
called as the vestibule
• It mainly contains the
• Hymen
• Vaginal orifice
• external urethral orifice
• Openings of the several ducts
• Hymen :
• Thin mucous layer which partially
occludes the vaginal opening.
• Vaginal orifice :
• It is the opening of vagina from the exterior
13. • OVARIES :
• These are female gonads
• These are paired present in the upper pelvic
cavity
• These are flattened ovarian bodies with
dimension of the 4cm( Length), 2cm ( width),
1cm ( thickness)
• Each ovary are attached at hilum by the
ligaments called ovarian ligaments, broad
ligaments , mesovarium ligaments
• Mesovarium gives rise to the germinal
epithelium
• Each ovary shows
• (1) medulla
• (2) cortex
14. • Each ovary consists of the :
• Germinal epithelium
• Tunica albuginea
• Stroma
• Ovarian follicles
• Graafian follicle
• Corpus luteum
• Interstitial cells
15. FUNCTIONS OF THE OVARIES:
Ovaries produces ova the female gamete by the
OOGENESIS
Ovaries produces the hormones like
ESTROGEN
PROGESTROGEN
RELAXIN
INHIBIN
16. OOGENESIS
• At the 7th or 8th month
of the intrauterine life
about 6 primordial
follicles are found in
the ovary
• But the time of the
birth there are only 1
million are seen
• At the time of the
puberty there are
3,00,000 to 4,00,000
17. OVARIAN HORMONES
• ESTROGEN :
• It is secreted by the theca interna cells of the ovarian
follicles
• The secretions of estrogen is predominant in the later
stage of follicular phase before ovulation.
• Function:
• promote cellular development
• Growth of ovarian follicles
• Increase in the spontaneous activity of uterine
muscles and sensitivity to oxytocin
• Increase the activity of cilia
• Reduces the PH of the vagina causing more acidity
• Development of breast
• Estrogen increases osteoblastic activity
18. PROGESTERONE
• It is secreted by the ovaries during the follicular stage
FUNCTIONS:
Promotes secretory activities of the uterine endometrium
Promotes secretory activities of the mucosal lining of the fallopian tubes
Promotes the development of the lobules and alveoli of the breast
Increases the reabsorption of the sodium and water
19. UTERINE TUBES
• Also called fallopian tubes
• They are two in number attached on either
side of the uterus
• Uterine tubes extend laterally from uterus to
ovaries
• Each uterine tube has been divided into
• Infundibulu
m
• Ampulla
• Isthmus
20. HISTOLOGY:
• MUCOSA
• MUSCULARIS
• SEROSA
• Mucosa is the innermost layer contains of ciliated
columnar epithelium
• Helps to move the secondary oocyte along tube
• Muscularis helps in the peristaltic movement
• Serosa lines the outer most layer
22. UTERUS:
• It is pear shaped hallow muscular organ
• It is situated in the pelvic cavity between the urinary bladder and
rectum
• It is 3” length, 2” width,1” thickness and 30-40 mgs weight
• Uterus is having
• FUNDUS
• BODY
• CERVIX
• Fundus is dome shaped present above the level of the
openings of the fallopian tube in uterus
• Body is middle portion of the uterus
23. • CERVIX :
• Inferior narrow portions of the
uterus
• It has two openings on either
sides
• Opens into uterus by internal os
• Opens into vagina by means of
external os
• Narrow canal is called as cervical
canal
24. WALL OF UTERUS:
• The wall of uterus is composed of
• Perimetrium
• Myometrium
• Endometrium
• Perimetrium is the outer most layer of the uterus
• Myometrium is middle layer made up of the smooth
muscle
• Endometrium is the inner most layer which is
highly vascular
• Stratum functionalis
• Stratum basalis
25. FUNCTIONS
• Serves as the pathway for the sperms to
reach the fallopian tube
• Uterus is site of menstruation
• Site of implantation of the fertilised egg
• Site of development of foetus during
pregnancy
• to provide blood supply to the ovaries
26. VAGINA
• Vagina is a fibromuscular canal lined by
the mucous membrane
• It is the female copulatory organ
• The diameter of the vagina increases2.5
cm to 5 cm
• It is situated posterior to the urinary
bladder and urethra
• At the lower end it is having hymen
• These acids create a low ph which retards
the microorganisms
27. FUNCTIONS
• It receives semen from the penis
during sexual intercourse
• Serves as a passage way for the
menstrual flow
• Serves as a passage way for baby
during child birth
• It secretes mucous for the lubrication
28. MAMMARY GLAND
• These are the modified sweet glands produces the milk
• These are present in both sexes but developed in females
• These are 2 in number present in pectoral regions
• These contain lobules alveoli
alveoli secondary tubules
secondary tubules mammary
glands
Mammary glands lactiferous
sinus
lactiferous sinus lactiferous
ducts
lactiferous ducts nipple
29. MENSTRUAL CYCLE
• The menstrual cycle is the regular natural change that occurs
in the female reproductive system
• The menstrual cycle starts with the first day of the period and
ends when the next period begins
• Hormone signals are sent back and forth between the brain and
the ovaries, causing changes to the sacs in the ovaries that
contain eggs (follicles) and the uterus
• The first part of the cycle prepares an egg to be released from
the ovary and builds the lining of the uterus
• The second part of the cycle prepares the uterus and body to
accept a fertilized egg, or to start the next cycle if pregnancy
doesn’t happen
30. • There are three phases
• Menstrual PHASE– first 5 days
• PRE OVULATORY PHASE 6th to 13th
day
• OVULATION – 14TH day
• POST OVULATORY PHASE
31. PREGNANCY
• It is sequence of events
• Fertilisation
• Implantation
• Growth of
embryo
• Fatal growth
• Delivery
32. • Fertilisation
• The process of union of male and
female gametes
• Out of million of sperms only
few i..e 1% reach the egg
• Sperm under goes capacitation
and penetrates in to the ova
33. IMPLANTATION
• In humans, implantation is the stage of
pregnancy at which the embryo adheres to
the wall of the uterus.
• At this stage of prenatal development, the
conceptus is called a blastocyst. It is by this
adhesion that the
• Embryo receives oxygen and nutrients from
the mother to be able to grow
34. EMBRYONICAL DEVOLOPMENT
• First two months of the development is called as embryonic devolpment
• During this period it is called as fetal period
35. • Pregnancy
• It is diagnosed by GRAVINDEX
TEST
• It is having three trimesters
• First trimester
• Second trimester
• Third trimester
36. • Amenorrhoea
• Morning sickness
• Salivation and changes in
disposition
• Irritability of bladder
37. SECOND TRIMESTER
• Pigmentation
• Changes in the shape and size of the uterus
• Intermittent uterine contractions
• Active fetal growth
• Palpation of fetal parts
38. THIRD TRIMESTER
• Pain less uterine contractions
• Fetal movements are easily known
• Uterine cavity enlarges
42. PATHO PHYSIOLOGICAL CHANGES
Polycystic ovary syndrome
• Polycystic ovary syndrome, widely known as PCOS, is an endocrine system disorder that
affects women in their reproductive years. Small fluid-filled sacs develop on the ovaries. It
is also known as or Stein-Leventhal syndrome
• symptoms
• irregular menses
• excess androgen levels
• sleep disturbances
• high stress levels
• high blood pressure
• skin tags
• infertility
43. • DIAGNOSIS:
• if women have at least two of three main symptoms — high androgen levels,
irregular periods, and cysts in the ovaries. A pelvic exam, blood tests, and
ultrasound can confirm the diagnosis.
• TREATMENT:
• Maintain a healthy weight. Weight loss can reduce insulin and androgen
levels and may restore ovulation.
• Limit carbohydrates. Low-fat, high-carbohydrate diets might increase
insulin levels.
44. SOME OF THE CANCERS
• Cervical cancer :A malignant tumour of the cervix , the lowermost part of the uterus.
• Ovarian cancer :A cancer that begins in the female organs that produces eggs.
• Uterine cancer :A type of cancer that begins in the uterus.
• Vaginal cancer :It occurs in the cells that line the surface of vagina.
• Vulva cancer :A type of cancer thar occurs on the outer surface area of female.
